On-board CO2 capture and storage with metal organic framework

Abstract

In general, this disclosure describes method of capturing and storing CO2 on a vehicle. The method includes contacting an vehicle exhaust gas with one or more of a first metal organic framework (MOF) composition sufficient to separate CO2 from the exhaust gas, contacting the separated CO2 with one or more of a second MOF composition sufficient to store the CO2 and wherein the one or more first MOF composition comprises one or more SIFSIX-n-M MOF and wherein M is a metal and n is 2 or 3. Embodiments also describe an apparatus or system for capturing and storing CO2 onboard a vehicle.

What is claimed is: 
     
       1. A method of capturing and storing CO 2  on a vehicle, comprising:
 contacting an vehicle exhaust gas with a first metal organic framework (MOF) composition, sufficient to separate CO 2  from the exhaust gas; 
 contacting the separated CO 2  with a second MOF composition, sufficient to store the CO 2 ; and 
 wherein the first MOF composition comprises one or more SIFSIX-n-M MOFs and wherein M is a metal and n is 2 or 3. 
 
     
     
       2. The method of  claim 1 , wherein the second MOF composition comprises a soc-MOF analogue. 
     
     
       3. The method of  claim 1 , wherein the metal comprises zinc or copper. 
     
     
       4. The method of  claim 1 , wherein the metal comprises Cu, Zn, Co, Mn, Mo, Cr, Fe, Ca, Ba, Cs, Pb, Pt, Pd, Ru, Rh, or Cd. 
     
     
       5. The method of  claim 1 , wherein the first MOF composition comprises bidentate organic ligands. 
     
     
       6. The method of  claim 1 , wherein the first MOF composition comprises bidentate N-donor organic ligands. 
     
     
       7. The method of  claim 1 , wherein the first MOF composition comprises a SIFSIX-3-Cu metal organic framework. 
     
     
       8. The method of  claim 1 , wherein the first MOF composition comprises a SIFSIX-3-Zn metal organic framework. 
     
     
       9. An apparatus for capturing and storing CO 2  on a vehicle, comprising:
 a filter component including a first MOF composition, in contact with an exhaust stream of a vehicle, wherein the first MOF composition is configured to separate CO 2  from the exhaust stream; and 
 a storage component including a second MOF composition, in fluid communication with the filter component, wherein the second MOF composition is configured to store the separated CO 2  ; 
 wherein the first MOF composition is selected from SIFSIX-M-3, SIFSIX-M-2-i, and combinations thereof; wherein M is a metal. 
 
     
     
       10. The apparatus of  claim 9 , wherein the second MOF composition comprises a soc-MOF analogue. 
     
     
       11. The apparatus of  claim 9 , wherein the metal comprises zinc or copper. 
     
     
       12. The apparatus of  claim 9 , wherein the metal comprises Cu, Zn, Co, Mn, Mo, Cr, Fe, Ca, Ba, Cs, Pb, Pt, Pd, Ru, Rh, or Cd. 
     
     
       13. The apparatus of  claim 9 , wherein the first MOF composition comprises bidentate organic ligands. 
     
     
       14. The apparatus of  claim 9 , wherein the first MOF composition comprises bidentate N-donor organic ligands. 
     
     
       15. The apparatus of  claim 9 , wherein the first MOF composition comprises SIFSIX-Cu-3. 
     
     
       16. The apparatus of  claim 9 , wherein the first MOF composition comprises a SIFSIX-Zn-3.
